Ordering information


Low Profile and Mini Series

Low profile in-line strainers require a minimum amount of space. To increase filter area the low profile tops can be matched with a longer bowl, (referred to as the Mini Series). Common applications for these strainers include home water treatment systems, floor cleaning equipment, and medical supply. The chart below shows reference dimensions for assemblies.


Regular (Intermediate) Series

This series is the most commonly used due to compact size yet large filter area. Some of the applications for this series include, dental supply, commercial and industrial pumps, agricultural and marine. The standard port is NPT. This series is also available with Hosebarb, BSP (Higher minimums apply).


Large Series

This series is our largest capacity strainers. They are used primarily in the same applications as the intermediate series, where increased flow rate and filtration area is required. Available in port sizes from 1" to 1-1/2".



In-line strainer tops are available in either black 20% glass filled polypropylene or white 6/6 nylon materials. Ron-Vik offers a variety of port types and sizes.

Male NPT - available in 1/8", 1/4", 3/8" and 1/2"
Female NPT - available in 1/8", 1/4", 3/8", 1/2", 3/4", 1", 1 1/4" and 1 1/2"
Hosebarb - available in 3/16", 1/4", 3/8" 
Quick connect fitting - available for 1/4" and 3/8" OD tubing


Ron-Vik offers five sizes of bowls, one for each of the product series. The top-bowl connection is a buttress thread to prevent cross threading. For application flexibility, the bowls are offered in 20% glass filled polypropylene, 6/6 nylon and clear nylon.



Ron-Vik offers three types of elements:
Wire mesh screen - the most common element, utilized in all in-line strainer assemblies. Standard mesh sizes are 20, 40, 80, 100 and 250 (depending on the body size). For strainer area please see the corresponding series Data. Options include:


Type 304 stainless steel is standard, however, Type 316 stainless steel and monel are also offered
Edges can be hemmed, soldered or molded with PVC
Finer mesh reinforced with a back up screen

Color coded synthetic caged screens available in 20, 40 and 80 mesh in both polypropylene and nylon.
Polyethylene filter (PE) - offered for the low profile, intermediate and large series. This filter is rated at 70 microns and is depth type filter making it non-cleanable.



Three gasket materials are offered to meet the various needs of Ron-Vik's customers. The gaskets are color coded to eliminate confusion when ordering replacements. The chart outlines the basic characteristics of the gaskets.



Technical Information

Cleaning Requirements

All wire mesh elements can be easily cleaned or replaced, without removing the entire strainer from the line, by removing the bowl. Do not use chemicals incompatible with the plastic components for cleaning.

Strainers may be mounted in any orientation providing that they are adequately supported to protect from undue stress and vibration.
Pressure Ratings

All of Ron-Vik's in-line strainer assemblies have been proven to perform at pressures up to 150 PSI at 70F and 100 PSI at 125F.
Pressure Spikes

Ron-Vik in-line strainers are not intended for applications where pressure spikes in excess of maximum pressure ratings can be expected.

Most of Ron-Vik's in-line strainers are eligible for NSF certification as part of your product. They are not individually NSF certified. Please contact us for specific information.
